AI Technical Summary
Existing sanitary napkins are prone to leakage during use due to loose adhesion or displacement of the wings to the underwear. In addition, leakage is also easily caused by insecure fixation at the front and back ends.
The sanitary napkin has Velcro hooks or silicone stickers on its wings and sides, with the Velcro hooks or silicone stickers in the second adhesive area being less than or equal to 10mm from the edge. A diversion layer and a leak-proof side are provided on the side away from the adhesive area to enhance the adhesive effect.
It effectively avoids the problems of displacement and leakage caused by poor adhesion between sanitary napkins and underwear, while improving the overall stiffness and anti-deformation ability of sanitary napkins and reducing the risk of leakage at the front and back.

The other two sides of the base body have second adhesive areas with hooks or silicone adhesive, and the distance between the hooks or silicone adhesive in the second adhesive areas and the edge of the base body at their respective ends is less than or equal to 10mm. The first and second adhesive areas are used to adhere the leak-proof sanitary napkin to underwear and are located on the same side of the waterproof base layer. An absorbent core layer is disposed on the side of the bottom body opposite to the first adhesive area and the second adhesive area, and is used to absorb liquid; And a hydrophilic surface layer, disposed on the side of the absorbent core layer opposite to the waterproof bottom layer, for contact with the skin.
2. The leakage-proof sanitary napkin as claimed in claim 1, wherein The hooks or silicone stickers in the first adhesive area are set continuously or intermittently; the hooks or silicone stickers in the second adhesive area are set continuously.
3. The leakage-proof sanitary napkin as claimed in claim 2, wherein The line connecting the two protective wings on both sides of the bottom body is the first axis, and the line connecting the second adhesive areas on the other two sides of the bottom body is the second axis. The first axis is perpendicular to the second axis. When the hooks or silicone stickers of the first adhesive area are continuously arranged, the length of the hooks or silicone stickers of the first adhesive area along the first axis is X, and the length along the second axis is Y, wherein X and Y satisfy: X≤50mm, Y≤60mm; the length of the hooks or silicone stickers of the second adhesive area along the first axis is Z, and the length along the second axis is M, wherein Z and M satisfy: Z≤20mm, M≤15mm.
4. The leakage-proof sanitary napkin as claimed in claim 1, wherein It also includes a flow guiding layer, which is disposed between the hydrophilic surface layer and the absorbent core layer, for guiding liquid from the hydrophilic surface layer to the absorbent core layer.
5. The leakage-proof sanitary napkin as claimed in claim 1, wherein The hydrophilic surface layer is further provided with leak-proof partitions on both sides that are opposite each other in the first axial direction. The leak-proof partitions are used to prevent liquid from leaking in the direction of the protective wing.
6. The leak-proof sanitary napkin as described in any one of claims 3-5, characterized in that, The bottom body is provided with two third adhesive areas at one end for placement on the back of the human buttocks. The two third adhesive areas are arranged on both sides of the second adhesive area along the first axis.
